operating year was 1981, when the society ran a total of 27 trains, including a notable trip over the former interstate narrow-gauge route to Quorn. In subsequent years it ran up to eleven scheduled trains per year. However, operations had to be briefly suspended on occasions during the late 1980s and 1990s, mainly because of unavailability of a serviceable locomotive. The society sent trains to Bruce, Hammond, Moockra and Carrieton, using hired NT class diesel locomotives, to recover track and civil infrastructure. Much of the recovered material was used within the depot at Peterborough West. The first organised motor section car excursions in Australia were hosted between 1994 and 1998, with entertainment including a live band at Eurelia on one occasion. In the society's last years of operation, it made a restored South Australian Railways motor inspection car available for hire. A hand powered section car ("Kalamazoo") race held at Black Rock yard in 2010 was the last event on the abandoned line. Rolling stock The society's revenue passenger cars were former Commonwealth Railways stock from the narrow-gauge Central Australia Railway between Marree and Alice Springs. Its steam locomotives were from the Western Australian Government Railways, including Pmr720, and W901 and W907 (the latter was never steamed). Diesel power was initially from Western Australia: former Commonwealth Railways NC1, which had been in the Lakewood Firewood Company's service, and Western Australian Government Railways Z1151. The society then obtained Commonwealth Railways NSU class locomotives 55 and 62 from those remaining at Marree. Early trains were hauled by Pmr720. However, the locomotive's boiler tubes failed in the late 1980s, leaving W901 as the only operational steam locomotive. Although plans were made to recommission Pmr720, they never eventuated. W901 experienced problems in later years through minimal maintenance and limited expertise of remaining volunteers. Some trains then became diesel-hauled or supported by small diesel power. Following the last train, W901's boiler was left full of water, causing concern about its possibly being affected by oxygen in the water. Former society members, including those involved with the recommissioning, undertook minor works in 2006 to minimise further deterioration. The locomotive became a static exhibit at the Steamtown Heritage Rail Centre in the Peterborough roundhouse. Diesel locomotive NSU55 was eventually recommissioned during 1998 after a considerable effort by a small band of volunteers. Track conditions throughout the roundhouse and on the mainline posed significant problems for its operation,
